For this reasons explicit solver LS-Dyna was used. In the fist part of this paper the ability of LSDyna material models to describe the ductile fracture of metals was investigated both with Lagrange and ALE behaviour of the mesh. The results of this testing phase were used to optimize the model of the bolt head trimming. Several geometrical versions were solved and the results were compared with a help of the cutting work and the contact force. As a next phase the experiment was carried out. The behaviour of the cutting force and the look of the separated material were evaluated.
